### 2.3. Equal-cost multipath

The above discussion has been simplified by considering only a single route to any destination. In reality, if multiple equal-cost routes to a destination exist, they are all discovered and used. This requires no conceptual changes to the algorithm, and its discussion is postponed until we consider the tree-building process in more detail.

With equal cost multipath, a router potentially has several available next hops towards any given destination.
